Slice the apple vertically into 1/8 inch slices, and submerge slices in the lemon water to prevent browning.

To assemble the “sandwiches”; take one apple slice, blot dry with a paper towel, and spread the surface with nut or seed butter. Take a second apple slice, blot dry, cut the center out with the heart cookie cutter and place on top of the peanut butter covered slice to make a “sandwich”. Reserve cut out pieces for smoothies or snacking, or discard if it is the core. Fill the heart shaped hole with the toppings of your choice!

Repeat with remaining apple slices.

Serve immediately or wrap individually in plastic wrap for up to 8 hours.
